Abstract
BackgroundThis study aims to investigate the value of oral contrast ultrasonography (OCUS) in the diagnosis of gastric cancer in elderly patients.MethodsOCUS data obtained from patients ≥ 60 years old were retrospectively analyzed and compared with gastroscopy results.ResultsAmong the 12,716 subjects examined by OCUS, 5021 subjects were ≥ 60 years old, which accounted for 39.48% (5021/12,716). Gastritis, gastric polyp, benign ulcer, and gastric cancer were detected by OCUS in 1099 patients. Among them, 196 patients underwent gastroscopy. Furthermore, ulcerative lesions were detected in 32 patients by OCUS and in 51 patients by gastroscopy, and the coincidence rate was 62.74%. Among these patients, gastric cancer was diagnosed in 18 patients by OCUS with a detection rate of 1.64% (18/1099) and detected in 19 patients by gastroscopy with a diagnostic coincidence rate of 94.73% (18/19). Furthermore, benign ulcer was detected in 14 patients by OCUS and in 32 patients by gastroscopy, and the diagnostic coincidence rate was 43.75% (14/32).ConclusionOCUS helps to timely detect senile gastric cancer and can be used as a suitable technique for the detection of gastric diseases.
Highlights
Gastric cancer is a prevalent malignancy in East Asia countries [1]
Cases of gastric cancer were diagnosed by oral contrast ultrasonography (OCUS), the detection rate was 9.18%, 19 cases were detected by gastroscopy, the detection rate was 9.69%, and the diagnostic accordance rate of ultrasound for gastric cancer was 94.73%. This is consistent with the results reported by Jun Lu and Chunmei Xu, in which the positive diagnostic rate of OCUS for gastric cancer was reported to be at 96.25% and 96%, respectively (Kappa = 0.972)
Gastric cancer in elderly patients is often diagnosed in the late stages
Summary
Gastric cancer is a prevalent malignancy in East Asia countries [1]. China has one of the highest incidence of gastric cancer in the world, and the overall survival rate is relatively poor [2]. Gastric cancer usually occurs in people > 50 years old. Methods: OCUS data obtained from patients ≥ 60 years old were retrospectively analyzed and compared with gastroscopy results. Results: Among the 12,716 subjects examined by OCUS, 5021 subjects were ≥ 60 years old, which accounted for 39.48% (5021/12,716). Ulcerative lesions were detected in 32 patients by OCUS and in 51 patients by gastroscopy, and the coincidence rate was 62.74%. Among these patients, gastric cancer was diagnosed in patients by OCUS with a detection rate of 1.64% (18/1099) and detected in patients by gastroscopy with a diagnostic coincidence rate of 94.73% (18/19). Benign ulcer was detected in 14 patients by OCUS and in 32 patients by gastroscopy, and the diagnostic coincidence rate was 43.75% (14/32)
